Radar Help !

[Hillbillyx-press]

Just installed a Furuno 1833 c radar .Dome is a rip 139 .Test trial last weekend at the OAK.Everything works but on screen boats in front of me are shown behind.Boats on port are shown on starboard. Everything is backwards. Cant get mode for Northup to change.  Thanks in advance. This forum has always been helpful.
